It was the most fun I've had creating something. I'm the guy who has to read every plaque at every historical site. Throughout this build, while referencing several pictures and videos, I got to read something interesting about nearly every part of a Katana. It was also fun to pull metal working, wood working, and knot tying all into one project.
Step 1: Project planning
From there I got together some other materials. I wasn't sure what all I would end up using but I had this to start.
